Collection:Modulating Control Valves

Selecting the correct modulating or actuated valve depends on the required control characteristics, medium properties, and operating conditions. The main valve types differ in design, control response, and suitability for various process environments:

• Proportional Solenoid Valves – Provide direct electrical control with fast response and fine adjustment capability.
• Modulating Ball Valves – Use a rotary ball element for proportional control. They offer high flow capacity and low pressure drop with high durability, suitable for general flow regulation.
• Angle Seat Valves – Pneumatically or electrically operated valves with an angled seat that minimizes flow restriction. Well-suited for high-pressure, high-temperature, or steam applications with frequent cycling, high durability.
• Globe Valves – Feature a linear motion plug and seat for accurate throttling and stable control across varying flow rates. Preferred for flow or pressure regulation in process systems.
• Diaphragm Valves – Utilize a flexible diaphragm to separate the actuator from the process media, ensuring contamination-free operation in hygienic, corrosive, or abrasive conditions.
• Disc Valves – Compact valves with a pivoting disc suitable for moderate flow control of gases or liquids.

Each valve design offers distinct flow characteristics (Kv/Cv) and control resolution, allowing selection based on the specific performance requirements of the process.
